I have a 97 tj with a 6cyl manual pcm that was transplanted from a 97 Cherokee xj! If the pcm is bad do I need to replace it with a 97 xj or can I get one for tj with the same engine and trans! I’m getting tps sensor A circuit high imput replaced sensor but nothing tech says it’s the pcm and told me it would cost twice as much if he did it for something I can replace in 10 min
